Default camshaft ticking noise

I have 66k on original motor on my 87 GN. Only mods made were upgraded chip, fuel pump / injectors, and adjustable waste gate (prior to my purchase). Under light acceleration it sounds like an exhaust leak. I have had it looked at by different mechanics and they can't find any signs of exhaust leak (looked at weak point on drivers side exhaust manifold and it was fine). Put it on the dyno and listened and the ticking wasn't there. It does come back when I drive it though. I have been using the Zinc additive since I have owned it for 7 years. Not sure if previous owners used it.
Can the camshaft/lifters be the cause of this tapping/ticking noise if the Zinc additive wasn't used by previous owners?
